Background / History

Luo Shu transmigrated into a mixed anime world after meeting a Raiden Shogun cosplayer at an anime convention. Arriving in Chiba City with no local identity or resources, he discovered the entity known as Void, which converts other people’s belief in his words and creations into Divine Authority Jade. 1

At Makuhari Seaside Park, he used Void’s information-reading function to operate as a fortune-teller. His first major client, Hoshino Ai, believed his warning about Kamiki Hikaru and changed the path that would have led to her early death. Luo Shu then convinced the Yukino sisters of his abilities and sold them a Divine Authority Jade-created protective ruby necklace. 2 3 4

After moving into Happiness Villa, he discovered that his rented room contained a Black Hole Phenomenon through which an evil spirit was attempting to descend. The encounter made him recognize that the new world contained supernatural forces capable of killing him, prompting him to pursue rapid growth through mass belief rather than small-scale fortune-telling. 4 5

Using an enhanced NTZ-48 pill, he wrote and illustrated Steel Land under the online identity “Merlin.” Its popularity produced far more Divine Authority Jade than his divination work, leading him to establish the Observer Net and create a live-action adaptation of Fate/stay night. 6 8 9

Luo Shu expanded the project into the global Heavenly Curtain, using humanity’s collective belief to create Heroic Spirits, Servants, Command Spells, and a staged Holy Grail War. Although he initially viewed many participants as tools for accumulating Divine Authority Jade, he repeatedly intervened to save people endangered by supernatural threats. 9 20 37

As his influence grew, he publicly demonstrated Servant-level and later godlike power, including defeating General K9 with a colossal Buddha manifestation. He eventually accepted the identity of the Eternal King, confronted Kaguya across repeated mental cycles and cosmic battles, and helped establish magic as a reality accessible to ordinary people. 90 164 166 199

Appearance

Luo Shu is a tall, refined young man whose appearance improved after his transmigration and repeated physical enhancements. He is commonly associated with elegant moon-white or white robes, though later transformations alter his hair color and aura. 1 8 47 87

• Initially wore a lavish robe embroidered with real gold and silver thread. 1 2
• Has notably smooth, jade-like skin and strikingly handsome features. 1
• Is tall and upright, with proportions described as an eight-head-to-body ratio. 1
• Frequently wears a moon-white feathered robe while acting as a magus or Holy Grail War Master. 8 42
• Manifesting Artoria’s template gave him cascading dark-blue hair. 47
• At Servant Rank, he wore white robes and possessed pale-blue hair and amber eyes. 87

Personality

Luo Shu initially presents himself as relaxed, playful, and self-assured. He is quick to improvise convincing identities, openly charges for supernatural assistance, and enjoys the attention generated by his mysterious persona. 3 4

He is highly strategic in his use of Divine Authority Jade. He weighs the cost of direct combat, spreads stories through online media to maximize belief, and deliberately manages the public’s perception of miracles so that famous figures and concepts retain their impact. 5 8 47 55

Despite his willingness to treat people as pieces in a larger plan, Luo Shu repeatedly risks himself to save others, including Higurashi Kagome and participants in the Holy Grail War. He also shows compassion toward people close to him and believes humanity can cultivate and improve rather than being inherently evil. 13 14 168

His detached confidence can become frightening when he invokes the Direct Death Demon Eye or confronts enemies far below his level. However, he can consciously return to a gentler demeanor, and his longing for an unreachable original home exposes a rare vulnerability. 66 280
